Question

Choose the correct statement.

• A. The force of attraction between the molecules of two different substance is called adhesive force.
• B. A strong adhesive force causes the liquid to spread all over the surface, on which it is poured.
• C. Both $\left(a\right)$ and $\left(b\right)$
• D. None of these.

Answer 1

The correct option is C Both $\left(a\right)$ and $\left(b\right)$

Adhesive force is the force of attraction between the molecules of two different substances.
$\Rightarrow$A strong adhesive force between the molecules of liquid and surface (over which liquid is poured) helps liquid to spread all over the surface.
$\therefore$ option $\left(c\right)$ is correct.
